OK, I'll give you my last reply.

This input file has some mistakes in the file names. Notably, filplot should be equal to filepp(1).

I don't understand why you should use both the &plot namelist and the average program. First you should understand WHAT you really want (and I'm a bit surprised that you haven't yet): 2D plots on a plane (using pp.x including &plot in the input) OR averages over those planes? In both cases you start from the 3D quantity, given by pp.x using the &inputpp namelist.
Please read CAREFULLY Doc/INPUT_PP.txt.

It's not clear what you are looking at! Of course, if you run pp.x changing x0, but then you look at the output of average.x (which reads filplot only, a file that does not change by modifying &plot), you will get always the same result.

> If positive, how could I get psi^2 on planes?

Specify appropriate values of x0 and e2. You should be able to find out by yourself which ones. You don't need to use average.x unless you want the averages over those planes.
